A burnt-out cargo ship carrying thousands of luxury cars, including Porsches and Bentleys, sank on Tuesday off the Portuguese Azores archipelago nearly two weeks after it caught fire, a port official said.

Joao Mendes Cabecas, the captain of the nearest port on the island of Faial, told Reuters the Panama-flagged Felicity Ace had sunk as efforts to tow it began due to structural problems caused by the fire and rough seas.

"When the towing started... water started to come in," he said. "The ship lost its stability and sank."

The blaze on the ship carrying around 4,000 vehicles made by Volkswagen Group from Germany to the United States, broke out on Feb. 16. The 22 crew members were evacuated on the same day.
